We should not be cutting deals with progressives. We should be opposing them and defeating them. They do not have America's best interests at heart.
Skill at making deals is only a positive characteristic if Trump is trying to accomplish positive things in those deals. If he's trying to raise taxes, socialize healthcare, spend more on bailouts, or appoint liberal judges, I don't care how good of a dealmaker he is. What good is his dealmaking skill if it results in him cutting a deal with liberals to have single payer healthcare?
Well, he’s saying he will negotiate and cut deals more in line with our interests. Negotiating for us rather than against us. Get the other side to move our way rather than us caving to their demands like the RINOs always do.
